SK-43D09 is a 4P3T (four-pole three-position) side-handle toggle switch from Sinyin Electronic' D Series ultra-compact lineup, designed for multi-channel three-mode synchronous control in extreme spaces. A single component integrates 4 independent circuit groups with 3 working states (e.g., OFF → A → B), replacing 12 single-pole switches, significantly reducing BOM cost, PCB area, and system complexity. The product features a nickel-plated metal shielding shell and side-insert DIP packaging, with a rated load of DC 50V 0.3A (directly marked on the drawing), and complies with RoHS 2.0 and REACH environmental directives. ⚠️ Note: Width is only 6.0mm (industry minimum), making it the narrowest 4P3T side-insert switch currently available from Sinyin Electronic. Strictly avoid mixing it with standard-width models such as SK-43D03.

SK-44D04 is a 4P4T (four-pole four-position) side-handle toggle switch from Sinyin Electronic' D Series, specifically designed for multi-channel + multi-mode deep selection. A single component enables 4 independent circuits to switch synchronously among 4 operating states (typical logic: OFF → Mode A → Mode B → Mode C), completely replacing 16 single-pole switches or MCU logic circuits, significantly reducing BOM cost, PCB area, and system failure rate. The product features a nickel-plated metal shielding shell and side-insert DIP packaging, with a rated load of DC 50V 0.3A (D Series general specification), compliant with RoHS 2.0 and REACH environmental directives. ⚠️ Note: 4P4T and 4P3T are fundamentally different in function—the former supports "four-state logic," while the latter only supports "three states." Before selection, be sure to confirm that the system requirement is "four-position mode selection."

SK-63D01 is a 6P3T (six-pole three-position) side-handle toggle switch from Sinyin Electronic' D Series basic line, designed for high-channel-density systems. A single component enables 6 independent circuits to switch synchronously among 3 operating states (typical logic: OFF → Mode A → Mode B), completely replacing 18 single-pole switches or complex logic circuits, significantly reducing BOM cost, PCB area, and system failure rates. The product features a nickel-plated metal shielding shell and side-insert DIP packaging, with a rated load of DC 50V 0.3A (D Series universal specification), and complies with RoHS 2.0 and REACH environmental directives. ⚠️ Note: 6P3T is fundamentally different in function from 4P3T/4P4T—the former supports "six-channel synchronous three-state," while the latter is four-channel or four-state. Before selection, be sure to confirm that the system requirement is "6-channel signal synchronous switching."

SK-63D03 is a 6P3T (six-pole three-position) side-handle toggle switch from Sinyin Electronic' D Series Extended Standard Version, optimized for industrial-grade high-reliability applications. A single device integrates 6 independent circuits with 3 working states for synchronous switching (OFF → Mode A → Mode B), replacing 18 single-pole switches, significantly reducing BOM cost and system complexity. The product features a nickel-plated metal shielding shell and a standard 2.54mm pin pitch DIP package, supporting wave soldering and SMT reflow soldering, with a rated load of DC 50V 0.3A, compliant with RoHS 2.0 and REACH environmental directives. ⚠️ Note: SK-63D03 and SK-63D01 are functionally identical (6P3T), but the former features an extended standard layout, while the latter may be a compact basic version; please select based on PCB process requirements.
